We have a team of 16 that build multiple very small Proof Of Concept (POC) apps. The average POC project size is < 2 months, maybe 2 developers. If the POC is a success, then the larger project scope is outsourced to another dedicated project team. Team members can be working on multiple projects at the same time.

This is not the usual scenario of 1 team working on 1 project so I would like to know is it something HP Agile Manager can support?

Can one HP Agile Manager tenant have multiple products/projects?

Would HP Agile Manager become unwieldy if used for this scenario, with multiple new projects constantly coming onstream?

Or.. are there any practices or configurations we should adopt going into HP Agile Manager to make this easier?

In short, is it doable? Any thoughts on this scenario and how to make it work are welcome

There are a couple of ways you can have this functionality in Agile Manager.

For managing the backlog, you can utilize the application attribute (go to Project configuration - applications). There you can define applications==project that will be managed in Agile Manager. You can later associate Theme/Features and User Stories to an application, which will enable the team to filter and track progress on the items per application, as they work on them

If each project has its own timeline, I would suggest creating a release per project

Per release you can configure teams, which in your case would most probably be the same for all releases/projects.

If the projects have a joint/shared timeline, you can create a single release in Agile Manager, and manage/track progress of items based on their application association.

Hope it helps. Would be happy to follow up if you have additional questions
